Paul Fernhout and Cynthia Kurtz are a husband and wife team who do research, programming and writing.

In 1998 we released three pieces of educational software
which are still available for free download.
You can also read about the history of these pieces
of software.

The Garden with Insight garden simulator
is an educational simulation that helps you learn about the
science behind gardening by playing with an open-ended simulation of a simple virtual garden.
Full source code is available.

The StoryHarp Audioventure Authoring System
supports interactive fiction development and conversational storytelling,
with optional voice input and output.
